1 Claim.

This invention relates to new and useful improvement in means whereby water meter valves can be removed and replaced in instances where water cannot be cut off at the street entrance due perhaps to ice and snow covering the usual stop box, or for other reasons.

The principal object of the present invention is to provide a water cut-off device which can be used immediately at the meter Valve to shut off the water while the valve is being removed and replaced.

Another important object of the invention is to provide a device of the character stated which is of simple construction and easy to manipulate.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings- Figure 1 represents a longitudinal sectional view through a meter valve and the improved appliance making up the present invention.

Figure 2 is a fragmentary longitudinal sectional View of the appliance after the valve has been removed.

Figure 3 is a section on the line 3 3 of Figure 1.

Figure 4 is a perspective view of the device alone. i

Figure 5 is a fragmentary perspective view of the device after the barrel and packing gland has been removed.

Figure 6 is a fragmentary perspective View of the screw and compressing rod.

Figure 7 is a section on the line 'I-'I of Figure 1.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a water meter pipe having a meter valve 6 at the end thereof. v

Numeral 1 generally refers to the present invention which consists of an elongated barrel 8 having a tapered and threaded end 9 for threaded disposition into the valve 6 to be removed.

The other end of the barrel 8 is threaded as at I0 for threaded disposition into a packing gland cap II in which is a gland element I2. Feedable through the gland element I2 is a tube I3 which is suitably secured as by welding to an elongated flexible tube I4 of less cross sectional dimension. The exible tube I4 terminates in a head I5 having an opening therein through which a flexible rod I 6 is slidable. Beyond the head I5 is a compressible packing body I'I preferably of rubber through which the end portions of the flexible rod I6 extends. This rod extends through a cap plate I8 bearing against the body I'I and is equipped with a nut I9 bearing against the cap plate I8.

The other end of the rod I6, and it may be noted that the rod tapers longitudinally, is secured to an elongated threaded member 26 which partly projects into the open end of the large tube I3. On this threaded member 20 is a nut 2I and interposed between the nut 2I and the adjacent end of the tube I3 is a sleeve 22.

In the use of this appliance, the meter is rst shut off at the valve 6. The meter coupling is then removed, freeing one side of the valve so that the threaded end 9 of the barrel 8 can be inserted. The packing gland I I, I 2 is now tightened. The valve 6 is now opened and the tube I3 forced inwardly so that the body I'I is passed through the valve 6 and into the pipe 5. The nut 2l is now rotated so as to pull on the exible rod I6, thus expanding the body Il, to the end that no further water can reach the valve 6. The packing gland I I, I2 can now be loosened so that the same can slide on the tube I3 and then the barrel 8 can be unscrewed from the valve 6. The barrel 8 and packing gland I I, I2, can be slid over the sleeve 22' and nut 2 I'. The valve 6 may now be removed from the pipe 5 and also slid over the sleeve 22 and nut 2I and a new valve replaced by sliding over the remaining portions of the appliance in the opposite direction and attached to the pipe 5.

The barrel 8 is now replaced over the tube I3 and screwed into the valve 6, the packing gland II, I2 tightened, the rod I6 loosened to permit contraction of the body Il after which the body Il is withdrawn through the new valve 6 into the barrel 8, after whichv the valve 6 can be closed and the appliance removed.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

Apparatus for stopping a pipe line extending from one side of a valve comprising a threaded barrel for attachment at one end to the other side of the valve and having a packing gland on the other end thereof, a tube for insertion through said gland, barrel and valve to position one end thereof in said line and having an enlarged disklike head on said end, an endwise adjustable rod extending through said tube and slidable in said head, said rod having a cap plate fast thereon, an expansible resilient plug interposed on said rod between said head and plate for compression said plug :ln the line, a larger rearend portion for tting in said gland to form therewith a seal, and a rearwardly ilared portion intermediate said reduced and larger portions for facilitating in- 5 sertion of the larger portion through the gland.
